Abstract The resurgence of interest in the hydrogen economy could hinge on distribution a safe and efficient manner. Whilst great progress has been made with cryogenic storage or liquefied ammonia, liquid organic carriers (LOHCs) remain attractive due to their lack need for temperatures high pressures, most commonly cycle between methylcyclohexane toluene. Oxidation release will be more if equilibrium limitations can removed by separating mixture. This report describes family six ternary...

Abstract The high‐power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) on lab‐scale devices trigger the need to develop scalable manufacturing processes accelerate their commercialization transition.

Light harvesting capacity of caesium silver bismuth bromide double perovskite need to be enhanced render this non-toxic and thermodynamically stable material suitable for photovoltaic applications, example as a top layer in tandem solar cells.

The low power-conversion efficiency (PCE) and reproducibility reported to date for roll-to-roll (R2R)-fabricated perovskite solar cells (PSCs) results from difficulty in controlling film quality. Here, we present a systematic comparison of the hot-deposition method, which induces crystal-growth-driven (CGD) formation, anti-solvent nucleation-driven (ND) one-step formation. Perovskite films produced by two methods show markedly different micro-structural optoelectronic properties; however,...
